WINDING ATTACHMENT FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 325,604, datedSeptember 1, 1885.

Application filed November 13, 1884. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES S. GUEENsEY,

of WVaterbury, in the county of New Haven, and in the State ofConnecticut, have invented certain new and useful Improvements infinding Attachments for \Vatches; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which- Figure 1 is anenlarged perspective view of my yoke" and its connecting parts separatedfrom each other, and Fig. 2 is a like view of the same combined witheach other and with the spring-barrel.

Letters of like name and kind refer to like parts in each of thefigures.

My invention relates to stem-win ding mechanism for watches; and itconsists, principally, in awinding-yoke having a click-spring that is apart of the same, and adapted to hold in place and pivot twowinding-wheels and a click or pawl, substantially as and for the purposehereinafter specified.

It consists, further, in a winding-yoke which is secured upon amovementplate by a single screw, and operates to hold in place and pivottwo winding wheels and a click or pawl, substantially as and for thepurpose hereinafter shown.

It consists, finally, in the combination of the winding-yoke with itsspring,the windingwheels, and the click with the movementplate andspring-barrel, substantially as and for the purpose hereinafter setforth.

In the annexed drawings, A represents a watch-plate, upon which issecured a yoke, 13, by means of a screw, C, that passes through thecenter of the latter, through a windingwheel, D, and into or throughsaid plate.

As seen in the drawings, the yoke B is formed from a flat piece ofmetal, has an elbow shape longitudinally and at its center, and each endis provided with a round opening, I), while from one side, near one end,a spring, Z), formed from the same piece, extends in a slight curve andin the same plane to and beyond the opposite end.

The screw C has a shoulder, c, at its lower end,which impinges upon theface of the plate A, and insures sufficient space between the latter andthe inner face of the yoke B to permit the wheel D to turn freely uponsaid screw, while between each end of said yoke and said plate is placeda stud, E, which has its ends reduced to enable them to fit into theopening b at such end and a corresponding opening provided in saidplate.

Upon the stud E, adjacent to the free end of the spring 12, is pivoted apawl or click, E, which is adapted to engage with the teeth 9 of anadjacentlyjournaled spring-barrel, G, and is held in such engagementwith a yielding pressure by means of said spring, that bears upon a pin,f, which projects from the outer face of said click between its pivotalbearing and outer end. A winding-wheel, H, pivoted upon the second studE, meshes at one side with the centrally-pivoted wheel D, and at itsopposite side with the usual steinactuated wheel, and enables the motionof said stem to be communicated to said springbarrel.

It will be seen that by my construction one screw operates to confine.in place the yoke, clickspring, click, and winding-Wheels,which partsare easily and quickly placed in or removed from position, and are notliable to derangement while in use.

Having thus described my invention, what I claim is- 1. A winding-yokehaving a click-spring that is a part of the same, and adapted to hold inplace and pivot two winding-wheels and a click or pawl, substantially asand for the purpose specified.

2. A winding-yoke which is secured upon a movement-plate by a singlescrew and operates to hold in place and pivot two windingwheels and aclick or pawl, substantially as and for the purpose shown.

3. The yoke B, provided with the openings b and spring b, the screw C,the stud E, the click F, having the pin f, and the windingwheels I) andH, in combination with each other and with the plate A, provided withthe openings a, and the spring-barrel G, j ournaled upon said plate,substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of July, 1884.

CHAS. S. GUERNSEY.
